Answer:
Mole Concept
Explanation:
From Mole Concept ; we know that ;
Mole ( n. ) = weight / Molecular mass = Vol. at stp / 22.4 L
weight / Mm = Vol. / 22400 ml
1 / Mm = 700 / 22400
1 / Mm = 1 / 32
Molecular mass = 32
ANSWER :- THE GAS IS O2 ( Oxygen )
O2 has 32 Molecular mass .

Answer:
Explanation:
V 1 =700 ml
P 1 =1 atm=760 mm Hg
T 1 =298 K
V 2
=?
P 2 =400 mm Hg
T 1 =288 K
Here number of moles is constant.
∴ T 1
P 1
V 1
= T 2
P 2
V 2
V 2 = T 1
2 ×P
P 1
1×V
2 ×T
= 298×400
760×700×288
=1285.37 ml
∴ Volume occupied by gas is 1285.37 ml.
